drm/nouveau: fix off by one in BIOS boundary checking
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 1b777d4d9e383d2744fc9b3a09af6ec1893c8b1a, 909d3ec1bf9f0ec534bfc081b77c0836fea7b0e2, acc887ba88333f5fec49631f12d8cc7ebd95781c.
Low priority for now. Upgrade to Linux Linux 1b777d4d9e383d2744fc9b3a09af6ec1893c8b1a, 909d3ec1bf9f0ec534bfc081b77c0836fea7b0e2, acc887ba88333f5fec49631f12d8cc7ebd95781c or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix off by one in BIOS boundary checking Bounds checking when parsing init scripts embedded in the BIOS reject access to the last byte. This causes driver initialization to fail on Apple eMac's with GeForce 2 MX GPUs, leaving the system with no working console. This is probably only seen on OpenFirmware machines like PowerPC Macs because the BIOS image provided by OF is only the used parts of the ROM, not a power-of-two blocks read from PCI directly so PCs always have empty bytes at the end that are never accessed.
